JDBC开发步骤

 

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class Demo01 {
    public static void main(String[] args) throws ClassNotFoundException, SQLException {
        //1.注册驱动
        Class.forName("com.mysql.jdbc.Driver");
        //2.连接数据库(获取连接对象)
        String url="jdbc:mysql://127.0.0.1:3306/java 1018?characterEncoding=UTF-8";
        String user="root";
        String password="123456";
        Connection con = DriverManager.getConnection(url,user,password);
        //System.out.println(con);
        //3.获得语句执行对象
        Statement sta = con.createStatement();
        String sql = "insert into sort(sname) values('小裙子')";
        //4.执行sql语句
        int row= sta.executeUpdate(sql);
        System.out.println(row);
        //5.释放资源(先开的后关)
        sta.close();
    }
}
